Specifically, the IBEX mission includes two single-pixel ENA cameras, namely the IBEX-Lo [1]} taking measurements from \(\sim \) 10 eV to \(\sim \) 2 keV [2]} (a new data release can be found in [3]}), and the IBEX-Hi [4]} that measures ENAs from \(\sim \) 520 eV to \(\sim \) 6 keV
[5]}. The INCA instrument on Cassini [6]}, part of the Magnetospheric Imaging Instrument (MIMI; [7]}) utilized a large geometry factor (G\(\sim \) 2.4 cm\(^2\)  sr) and a broad field of view (FOV; 90\(^{\circ }\times \) 120\(^{\circ }\) ), possessing a high sensitivity to detect very low ENA intensity events in the heliosphere and image large parts of the sky sphere over the energy range of \(\sim \) 5.2 to 55 keV [8]}.
